Patented June 3, 1930 ALBERT s. MORRIS, yonYoevitnirivn, CALIFORNIA i DEvIe non Iiekne WINDSHI'LD "WIPES "Thisinvention relates to a'devieeto beused in combination with `an automobile Wind# shield Wiper and is for the purpose of holding the Wiper in a position Where it Will not in- ,5 te'rfer'e Vvvith the driversl vision when the Wiper is not in operation-i i i interfere vvithjhis"vision,` butythe jarring of the cali when it is moving scionjeausee the Wiper to move downvvad Where it Will shovvl thedrivers vision. f o,

Itis-therefore ahi object ofthe present inlveiiti-on to provideV an exceptionally simple d improved device for'positivelyholdirfig through the Windshield" nd interfere'vvith the" wind-shield Y wiper out, fof 'the drivers vision Whenit is notin operation.V l, 'L

views,- ythe numeral 8 designates a threaded Amember having a hole 9,-thatflong'itudinall5`f extends therethrough as'jshown in Figure vv2 afnd aV slot 10 in one end thereof as shown in Figure 3. 4The end ofthe threaded member 'oppositeltheslotted endis reduced to al smaller diameter than` the' threadedrporti'on as designa-ted by'v 'the 'nu'i'eral Sa, and a coiled spring' 12 is-mouhted on the said reduced portionv and zed thereon preferably by being spotpweldedxso as to form a'unit with the lthreaded member 8. i A sleeve 14 is mounted over the coiled spring 12 and isfastened detachably to thethreadedstem 8 asshovvn in Figure2. A handle .15 having aprjectingl portion lris` provided `'and one end of the coiled spring l2 is mounted on the projecting portion 15aA and is spot Welded thereon in a similar miimerl as the opposite fend of theV said 'spring islixed` on the" threaded member 12 Y Y Thepjffefie mtis for hominguie Wiper isshovvnas comprising a hook shapedfmember 1,6 formed preferably as shOWii'in' 'Fig-i but may be made out of any suitable material that will serve the purpose of the invention. The inner end 16a of the wire is preferably made square to fit into a square hole 15b provided in the projecting end of the handle 15. The said holder 16 is then substantially held in the handle by means of a set screw 18 as shown in Figure 2. Lock nuts 19 and 20 are provided and threaded on the threaded member 8 to substantially hold the device on the wind-shield frame. mount the device in position a hole 21 is drilled through the top of the wind-shield frame, a suitable distance from the wiper 22, and the threaded member 8 is mounted through said hole and is substantially held on the frame by the lock nuts, which are applied against the frame as shown in Figure 2. The hook 16 is removed from the handle 15 when the threaded member is mounted in the windfshield frame and is put back in the handle-when the device is ready for operation.

When it is desired to hold the wiper in locked position where it will not interfere with the drivers vision, the handle 15 is pushed forward, as shown in Figure 2, until the hook 16 is free fromthe slot 10 inthe threaded hollow member 8 and the handle is then turned toward the wiper to a position where the end 16b thereof extends beyond the wiper. At this point the handle may be released and` the compressed spring 12 will pull the hook over the wiper. As one end of the spring is fixed on the member 8, which is stationary with the wind-shield, and the other end of the-spring is fixed on the handle, it will be seen that when the said handle is turned with respect to the wind-shield to a position where the hook willfcatch the wiper, a twisting strain will be applied on the spring which will cause the hook`16', which is fastened to the handle, to immediately snap back to its normal and locked position as soon as the handle is released, and will thus carry the wiper to the locked position with the hook. When it is desired to operate the wiper, the handle is pushed forward to a position where the end 16b of the hook will free the wiper, which will permit it to be operated the same as usual.

A portion of the end of the member 8, across the slot 10, is formed curved so that the hook member 16 may be easily forced back in its normal and locked position. From the foregoing it will be seen that the invention con sists primarily in the'providing of a device having a hook shaped memberthereon, and mounting the said deviceon the wind-shield in a position where it will be free from the operation of the wiper, and providing means whereby ythe hook shaped member can be moved to where it can catch the wiper and then turned to a locked osition where the wiper will be completely ree from the drive ers vision.

Having thus illustrated and described a` When it is 'desired toV certain form of construction and arrangement of parts pertaining to the invention, it is to be understood that the improved features may be. embodied on or in combination with any type of automobile wind-shield wiper, and that the part-s may be built up in any suitable manner, the present illustration not being utilized as indicating the only arrangement or form of construction into which the said parts may be made; and it is desired to include in this application for Letters Patent of the United States of America, any and all patentable novelty that exists in the invention disclosed and all that comes within the fundamental principle of the invention as set forth in the claims hereinafter mentioned.

What is claimed is:

1. A device of the character described, for use in combination with a wind-shield wiper, said device comprising a hollow member that is constructed to project through the wind shield; means for fastening the hollow member to the wind-shield; a coiled spring fastened to the end of the hollow member that extends on the inside of the wind-shield; a handle fastened to the coiled spring; a hook shaped member mounted in and through said hollow member and coiled spring and fastened to said handle.; a slot provided in the end of the hollow member that extends beyond the outside of the wind-shield; said coiled spring being adapted to resiliently hold said hook shaped member in said slot; said hook shaped member being adapted to be moved forward and turned in one direction to catch the wind-shield wiper and turned in the other direction and automatically heldin said slot to hold the wiper where it will be free from the drivers vision when it is not being operated.

2. A device of the character described, for use in combination with a wind-shield wiper, said device comprising a threaded tube that is constructed to project through the windshield; llock nuts for fastening said threaded tube to the windshield; a coiled spring fastened to the end of the tube that extends on the inside of the wind-shield; a handle fastened to the coiled spring; a hook shaped member, mounted in and through said threaded tube and coiled spring, fastened in said handle; a slot provided in the end of the tube that extends beyond the outside of the wind-shield; a curved portion formed on said end, on one side of said slot; said coiled spring being adapted to resiliently hold said hook shaped member in said slot; a tube mounted over the coiled spring and fastened to said threaded tube; said handleA being slidable in said tube, to move the hook mem'- ber from said slot, and the spring being tensioned to rotate said hook member against the wiper, and also retract said member into said slot.

3. Ina device of the character described, a hook shaped member having a straight ste-m slidably and rotatably mountable through the frame of a Windshield, a handle on said stem 5 by which the stem may be pushed forward,

means to retract said stem and rotate the hook member against a reeiproeatable Wiper, and means to lock said hook member in position.

In testimony that I claim the foregoing I lo have hereto set my hand this 13th day of August, 1929.
